[0026] Please refer to Figures 1-4 , a segmented quick-change cylindrical pulling-out device, which includes a mounting base 1. On the front surface of the mounting base 1, two parallel guide rails 5 are installed. On each guide rail 5, two sliders 20 are installed. A left mounting base 28 is installed on the upper and lower two sliders 20 on the left side, and a right mounting base 29 is installed on the upper and lower two sliders 20 on the right side. On the outer side surfaces of the left mounting base 28 and the right mounting base 29, a pair of pressure plates 2 are symmetrically installed at the upper and lower positions; a clamping plate 8 is inserted into each pair of pressure plates 2. Each pressure plate 2 is provided with 3 indexing pins 17. By tightening the indexing pins 17, the clamping plate 8 is clamped in the pressure plate 2. The clamping plate 8 has various specifications. By replacing different specifications of the clamping plate 8, the pulling-out function of cylindrical parts with a diameter between 100 mm and 300 mm can be realized. The cylindrical parts with a diameter between 100 mm and 300 mm include cylindrical parts with diameters of 100 mm - 150 mm, 150 mm - 200 mm, 200 mm - 250 mm, and 250 mm - 300 mm.

[0027] On the front surface of the mounting base 1, a pair of power mechanisms are symmetrically arranged on both sides of the left mounting base 28 and the right mounting base 29. The power mechanism includes a cylinder fixing seat 4 installed on the front surface of the mounting base 1. A clamping cylinder 3 is installed on the cylinder fixing seat 4. A floating joint 27 is installed at the head of the clamping cylinder 3. A floating block 26 aligned and cooperating with the floating joint 27 is installed on the outer side surface of the connecting rod connecting block 32.

[0028] The left mounting seat 28 and the right mounting seat 29 are symmetrically installed with connecting rod connecting blocks 32, and the inner side of each connecting rod connecting block 32 is symmetrically installed with a side connecting piece 11. The middle connecting piece 10 is connected between one end of the two side connecting pieces 11 by a pin shaft 18. The center position of the middle connecting piece 10 is installed with a mounting shaft 15 through a gasket 9. Two groups of propulsion protection mechanisms are installed on the back side of the mounting seat 1 and in contact with the end face of the mounting shaft 15. Each group of propulsion protection mechanisms includes an oil-free bushing 21 that is installed with an opening at the center position of the mounting seat 1 and is located on the same axis as the mounting shaft 15. A tapered pin 22 is installed inside the oil-free bushing 21. It also includes a cylinder seat 30 that is arranged on the back side of the mounting seat 1 and is located on the same axis as the tapered pin 22. A movable joint 24 that is installed in contact with the tapered pin 22 is installed in the cylinder seat 30, and the movable joint 24 is connected to the latch cylinder 23.

[0029] In the above embodiment, a limit block fixing seat 13 and a limit block support 16 are installed on the front of the mounting seat 1, and a limit block 14 is installed on both the limit block fixing seat 13 and the limit block support 16; there are two limit block fixing seats 13, which are located below the clamping cylinder 3, and there are two limit block supports 16, which are located on the upper and lower sides of the mounting shaft 15.

[0030] In the above embodiment, a pair of sensor brackets 12 are symmetrically installed on the upper end surface of the mounting seat 1, and a sensor 7 is installed on each sensor bracket 12; a pair of induction brackets 6 are symmetrically installed on the upper end surfaces of the left mounting seat 28 and the right mounting seat 29, and a induction screw 19 is installed on each induction bracket 6.

[0031] The working principle of the above embodiment is:

[0032] During use, first insert the clamping plate 8 of the corresponding cylindrical part diameter section into its pressure plate 2. The initial state of the left and right end clamping cylinders 3 is set to retracted, and the initial state of the pin cylinder 23 is set to retracted. The left mounting seat 28 and the right mounting seat 29 are connected by a linkage mechanism composed of an intermediate connecting rod 10 and connecting pieces 11 at both ends, which has a synchronous operation function. When the entire cylindrical part product is in place, the left and right end clamping cylinders 3 start to extend. The product specification section corresponding sensor 7 obtains a signal. The sensor 7 can perform the cylindrical part specification section detection function by detecting the induction screw 19 above the induction bracket 6 on the left mounting seat 28 and the right mounting seat 29. At this time, the pin cylinder 23 corresponding to the sensor 7 acts to make the clamping plates 8 on both sides hold the cylindrical part tightly. After the cylindrical part is held tightly by the clamping plates 8, the sensor 7 of the cylindrical part specification section gives a signal again, causing a pair of pin cylinders 23 on the sensor signal side to act. The pin cylinder 23 pushes the movable joint 24 to act, the movable joint 24 then pushes the taper pin 22 to act, and the taper pin 22 then pushes the mounting shaft 15 to act. Thus, while the cylindrical part is subjected to the clamping force of the transverse clamping plates (8) on both sides, it is also subjected to the longitudinal force given by the mounting shaft 15, prompting the clamping plates 8 to lock the cylindrical part tightly. At this time, the cylindrical part can be pulled out. This pin cylinder can play a protective role in pulling out the cylindrical part, preventing the cylindrical part from falling off and making the device safe and reliable.

[0033] After the cylindrical part is pulled out, the rear pin cylinder 23 retracts, and the left and right end clamping cylinders 3 retract. The pressure plate 2 loosens with the clamping plate 8, and then the cylindrical part can be taken out. By replacing the clamping plate 8 for holding the cylindrical part and repeating the above working steps, the pulling out of cylindrical parts of multiple specifications can be achieved, such as specification sections of 100mm - 150mm, 150mm - 200mm, ......, 250mm - 300mm.
